Which of the the following could be the ratio between the lengths of the two legs of a 30-60-90? check all that apply. (a)sqrt2: sqrt3 (b)1: sqrt2 (c)sqrt2: sqrt2 (d)2sqrt3: sqrt6 (e)1: sqrt3 (f)sqrt3: sqrt3

This is worth remembering:

In a 30-60-right triangle,
-- the side opposite the 30 is 1/2 the hypotenuse
-- the side opposite the 60 is (1/2 the hypotenuse) times (square root of 3).



I believe Choice-'E' is the only one you could make with the above rule.

Angle onp = 43°angle lno = 137°angle mnp = 137°
